摘要
文章给出了2004年国家电网公司系统7．2-550kV高压断路器的装用情况，重点对其在运行中的事故及障碍情况分别按类型、电压等级、事故责任分布进行了统计分析，对发生拒动、误动、绝缘、栽流、外力及其他不同类型故障的原因进行了分析，指出了在专业管理中存在的问题，并提出了技术对策，以供电力系统运行部门和高压开关制造厂参考。
The paper gave the installation and operation conditions of 7.2 - 550 kV high voltage switchgear in SGCC system in 2004, which was analyzed according to the type, voltage grade and the responsjbility of fault and obstacle condition in operation. The reasons for resisting to move, miss operation and different types of fault caused by insulation, carried current and outside force were statistical to analyze. It is pointed out the existent problems in professional management, and the technical countermeasures are put forward, which can be as reference for power system operation department and high voltage switchgear manufacturer.
